Sweet Potatoes vs. Potatoes: Which are really healthier?

Sweet Potatoes vs. Potatoes: Which are really healthier?


Let's get to the bottom of this never-ending debate.

By Brian St. Pierre


Sweet potatoes vs. potatoes: A nutritional debate fueled by misinformation, baseless ‘superfood’ obsessions, and carbohydrate phobias. Here’s how these tubers compare — and why both deserve a place in your diet.


A few years back, some crazy nutrition enthusiasts decided to figure out whether white or sweet potatoes were “healthier”.

One group compared the glycemic index and load of sweet potatoes vs. potatoes. They suggested that since white potatoes tend to be higher, they should be avoided.

Another group suggested that sweet potatoes are a vitamin A ‘superfood’, putting them way ahead of their white potato competitors.

And, of course, the carbophobes had their own take: All potatoes should be avoided because they’re too high in carbs and all those carbs will mess with your insulin regulation and cause fat gain.


Check out this infographic to learn more about white and sweet potatoes, and why you should consider including both in your diet

CLAIM: AVOID POTATOES
BECAUSE OF GLYCEMIC LOAD

Worried potatoes will make your blood sugar and appetite spike?
Here's what the evidence says.

BOTH POTATOES AND SWEET POTATOES FALL IN THE MIDDLE
TO HIGH RANGE ON THE GLYCEMIC LOAD (GL) SCALE.

CLAIM: AVOID ALL TUBERS
BECAUSE OF CARBS

Think the carbs will cause weight gan? Actually, the carbs in potatoes and sweet
potatoes are mostly starch and fiber, which help you stay lean and healthy

« Stimulate blood flow to the colon « Decrease risk of colon cancer

AND SWEET POTATOES

potatoes, beans, lentils, fru, or whole grains. Then adjust portion sizes up or down based on:
